'J. A.- BUOKLEY & C. J. KOEFOED VBNTILATING CARS.

No. 355,587. Patented Jan. 4, 1887'.

JOSEPH A. BUCKLEY AND CHARLES J. KOEFOED, OF SAN FRANCISCO, CAL.

VENTl LATI NG CARS.

SPECIFICATION forming part of Letters Patent No. 355.587, dated January 4, 1887.

Application filed May 1, 1886.

To all whom, it 777/661] concern:

Be it known that we, JOSEPH A. BUOKLEY and CHARLES J. KOEFOED, both of the city and county of San Francisco, State of California, have invented an Improvement in Ventilating Cars; and we hereby declare the following to be a full, clear, and exact description of the same.

Our invention relates to a devicefor ventilating cars by constantly removing from the car the foul and heated air which accumulates therein.

It consists in the combination of devices hereinafter described and claimed.

Referring to the accompanying drawings for a more complete explanation of our invention, Figure 1 is a side elevation of a car showing the arrangement of pipes in connection with the suction-fan. Fig. 2 is atransverse section of the car. Fig. 3 is a bottom view showing one of the wheel-trucks and the suction-fan. Fig. 4 is a perspective view showing the relative arrangement of the fans, driving-belts, and connectingpipes.

AA are wheel trucks, such as are employed beneath ordinary railway carriages, which are supported upon the trucks by means of swivel pins or bolts, to allow the trucks to move independently in turning curves.

Upon the truck-frames we fix the suctionfans B and O, standing in opposite directions, so that when the car is running in one direction one of the fans will be acting, and when it runs in the opposite direction the other will be at work.

Upon the axles E of the car-wheels, or to the inner sides of the wheels, are fixed beltpulleys F, friction-wheels, or gears, and from these intermediate belts or gearing transmits the power to the fan shaft, the necessary speed being provided to' cause the'fan to operate properly. 4

Flexible pipes or hoseG are connected with the ingress or supply openings of the fans, and these connect with fixed pipes H upon the body of the car. By this construction the trucks and the fans, with the mechanism attached, may move freely to suit the curves of the road, and the connection between the fans and the rigid pipes will be properly maintained by the flexible hose without danger of breaking or separating the joints.

Each fan may be connected with the pipe IE[ and be provided with cocks and valves,

Serial No. 200,872. (No model.)

which may be opened or closed at pleasure, so that when one fan is inoperative the connection with it may be closed. The pipes H lead upward into the body of the car, and one or'more pipes, I, connect with their upper ends and extend through the upper portion of the car. These horizontal pipes are provided with openings, and preferably have short pipes with abell or funnel mouth expanded ends, through which the air may enter the pipes from the upper portion of the car. As many of these openings may be made in the pipes as may be necessary or desirable, and theyare provided with stop-cocks, so that one or more of them can be closed at pleasure. By this construction a constant draft of air is provided from the upper portion of the car through the pipes I and H into the suctionfan, and this air is discharged through the ordinary discharge-openings of the fan.

Fresh air-.will be supplied within the car constantly either through the ordinary openings, or, if desired, special openings may be made and properly screened or protected, so as to prevent dust from being admitted to the car. By this means wc are enabled thoroughly to ventilate the cars at all times and prevent an accumulation of foul air within them.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is- I The suction-fans supported upon the wheelact when the car is moving in one direction and the other when the car is moving in the opposite direction, pulleys upon the car-axle by which the fans are rotated, pipes fixed to the body of the car and having a flexible connection with the inlet of the fan-casing, horizontal pipes connected with these and extending along the upperv part of the car, in combinationwithdownwardly-extendingshort pipes having funnel shaped openings and valves or stop-cocks in each of said pipes by which the draft through each and all may be regulated, substantially-as herein described.

In witness whereof we haye hereunto set our hands.
